PROBLEM TO BE SOLVED: To provide a catheter assembly capable of puncturing or detention in a compact state.SOLUTION: A catheter assembly 10 includes a catheter 12, a catheter hub 14 provided in a base end of the catheter 12, and an inner needle 16 removably inserted to the catheter 12 and the catheter hub 14. The catheter hub 14 includes a hub main body 20 formed with a hollow part 21 communicating with a lumen of the catheter 12, and a patagium part 24 that is provided in the hub main body 20 and can deform from a first state in which at least a part is curved along an outer peripheral surface of the hub main body 20 to a second state of projecting in a patagium shape from the hub main body 20.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】コンパクトな状態で穿刺または留置を行うことが可能なカテーテル組立体を提供する。【解決手段】カテーテル組立体１０は、カテーテル１２と、カテーテル１２の基端に設けられたカテーテルハブ１４と、カテーテル１２およびカテーテルハブ１４に抜去可能に挿入された内針１６とを備える。カテーテルハブ１４は、カテーテル１２の内腔と連通した中空部２１が形成されたハブ本体２０と、ハブ本体２０に設けられ、少なくとも一部がハブ本体２０の外周面に沿って湾曲した第１状態から、ハブ本体２０から翼状に突出した第２状態へと変形可能な翼状部２４とを有する。【選択図】図１
